How to install Ubuntu 14.04 on encrypted MBR partitions

This tutorial shows how to install Ubuntu 14.04 on encrypted MBR partitions. It is only slightly different from Manual full disk encryption setup guide for Ubuntu 13.10 & Linux Mint 16. The only difference: A partition mounted at /home is not part of the mix. But there’s no real reason for not creating a separate partition for home. I just wanted to demonstrate that this is possible with Ubuntu 14.04′s installer after a comment to the contrary by a site visitor.

The objective here is to install Ubuntu 14.04 by creating a custom set of encrypted partitions. To prove that this works, I first created these partitions in a virtual environment (using VirtualBox), with 250 GB of storage, then repeated the procedure on real hardware with a 320 HDD. Keep in mind that this is a general guide for creating encrypted Ubuntu 14.04 partitions on a computer with MBR partitions (Legacy BIOS) and with Ubuntu 14.04 the only OS on the hard disk drive (HDD). You should, however, be able to use this same instructions to install Ubuntu 14.04 alongside any other OS on the same HDD.
